Do I really need 4:10 axles?

Thanks! I will get the fuel system renewed as soon as I can.
What is the best timing setting to compensate for the new fuel?
We had a baby Monday last week so I can't do much now.
I appreciate all the help, I will post any changes as they come.

A p pumped crew cab would be sweet! I'm full up on projects rite now.
If u can squeeze a little more power and efficiency out of this rig I would be very happy.

Congrats on the little tyke. My youngest is 5 so babies are a bittersweet thing to me, miss them but 4 kids is definitely enough.

It sounds like you have realistic expectations out of your rig. Good luck with everything.

Set your timing at about 9.7 deg btdc by the pulse method and you'll be good to go.
If you ever get a yen for a brownie, theres a yard down in OR, Andersen Bros, that has a stinkload of the things ( they're all over the place up there, folks still like to pop them on log trucks behind 10 speeds etc )

Really nearly every post has been correct. I run a set of 3.55 gears but my engine has been built to use those gears towing heavy too. I really think I could be better of with a set of 3.73 or 4.10 gears.. I'm due for a grear change. There is lots of slop in the ring and pinnion gear feel.. Its hopefully not the yoke to pinnion shaft feel...
